The “warts-and-all” film reportedly includes an emotional letter Davis wrote to his protege Houston back in 2001 pleading with the singer to get help years before she died in 2012 after battling substance abuse. Davis penned the letter after the singer looked gaunt at a Michael Jackson anniversary concert, according to The Hollywood Reporter.

“Of course I know that your power of denial is in overdrive dismissing everything I and everyone else is saying to you,” Davis wrote. “I join your mother in pleading with you to face up to the truth now, right now, and there is no more time or postponement. You need help and it must begin now.” She died the same day as Davis’ annual star-studded Grammy pre-party.

The film by Chris Perkel follows Davis’ rise to head of Columbia Records by age 35 and his discovery of classic acts like Janis Joplin, Chicago, Blood Sweat & Tears, Santana and Aerosmith, as well as his skyrocketing career building major record labels like Arista and J Records. Davis also guided the careers of Simon & Garfunkel, Bruce Springsteen, Billy Joel, Patti Smith, The Grateful Dead, Dionne Warwick, Keys, Hudson, Rod Stewart and Diddy, and the film reportedly includes interviews with many of those he mentored.
